But no, admitting they were rude and graceless, is not the act of a super power.
No, what Panetta is here to do is to try and sign New Zealand up to his team trying to encircle and contain the rampant dragon that is China. It's hardly a new story. Half a century ago it was the yellow peril and filthy commies swooping down through Asia and into the Pacific. Now these devilishly tricky foes have transmogrified into expansionist capitalist roaders, pockets overflowing with American dollars, spreading out into the world seeking markets and influence the US regards its own.
Last Saturday, in a press briefing en route to Tokyo, Panetta told his media entourage his trip to Japan, China and New Zealand was "an opportunity to further advance our strategy of rebalancing towards the Asia Pacific ... What we want to do is obviously deepen our engagement in this part of the world, across the entire US Government". He said it was a combined military, diplomatic and economic push.
It was not just about asserting US presence in the area, "but also maintaining and strengthening a system of rules and norms and institutions in Asia that have brought decades of security and prosperity to the region ...".
He said "I will be visiting three countries that have an important role to play in our rebalance strategy."
Talk about flattery. New Zealand mentioned in the same breath as Japan and China and "important".
The long-time pariah is now "a very valued partner to the United States and we deeply appreciate the role they've played in Afghanistan ...". He said the purpose of his trip to New Zealand "is to see what opportunities exist to try to deepen our defence co-operation".
When you look at the devastation that is Iraq and Afghanistan and the upheavals throughout the Muslim world and read of US unmanned Predator and Reaper drone aircraft bombing village wedding parties by remote control, is this a "friend" or "valued partner" we really want to get any closer to?
We joined them in the Vietnam calamity, and the Afghanistan debacle. Now they want us to join them in putting some sort of corset around China.
At least with both Vietnam and Afghanistan, we had no previous relationship to ruin. But in asking us to join him in some sort of containment of China, Panetta is asking us to take his side against our second biggest trading partner.
The 2008 New Zealand China Free Trade Agreement, the first such agreement with a western country, along with this year's celebrations of 40 years of diplomatic relations, underlines the importance New Zealand places on our relationship with China.
In the year to June 2011, exports to China grew 37 per cent on the previous year, totalling $5.6 billion and amounting to 12 per cent of total exports. Only Australia took more, The United States came third, receiving 8.5 per cent.
Imports followed the same pattern, Australia providing $7.4 billion worth, China, $7.1 billion and US, $5.1 billion.
It's nice of Panetta to drop in. But the price he asks is too high.
